Objective:
to verify the correct assessment rate when using direct visual comparison in the cervical dilation measures in hard-consistency cervix simulation models.
Method:
an open-label and randomized study conducted with 63 Obstetrics students that were designated either to use direct visual comparison in a dilation guide or not. The students estimated cervical dilation blindly in simulators with different dilations. The primary outcome was the correct assessment rate.
Results:
the students performed 141 tests. A higher correct assessment rate was found in the Experimental Group than in the Control Group (47.3% versus 27.2%; p<0.001; Odds Ratio = 2.41; 95% Confidence Interval = 1.62-3.58).
Conclusion:
the direct visual comparison increased precision of the cervical dilation assessment in cervix simulation models, with the possibility of being beneficial in laboratory training. Brazilian Registry of Clinical Trials No. U1111-1210-2389.
